Voucher posting criteria

Hello,

We are PeopleSoft 9.2. Recently, we upgraded from PeopleTools  8.55.12 to 8.57.08 and from Image# 21 to 33. In image# 21, if a voucher is approved/matched, it becomes available for voucher posting process irrespective of its accounting date. That is to say, even if the accounting date on Voucher Information tab is not within the current AP Open Period range, the voucher posting process will select the voucher. However, in the new Image#31, even if a voucher is approved or matched, it is still not eligible for voucher posting unless the accounting date falls within the current open period range.
